Summary
Sentinel Majors are the same basic design as the Sentinel, with three notable exceptions. One is the gold-colored armor plating replacing the normal silver-colored armor plating. Whether this is simply a color difference or a different armor alloy altogether is unknown. The second difference is that the Sentinel Majors are armed with Advanced Sentinel Beams that fire blue-colored lasers instead of the weaker orange-colored beams that normal Sentinels use. The third is the Sentinel Major's energy shielding, which can absorb more damage than a normal Sentinel.
